I ordered a Blue Jeans sub-woofer cable. I had a 12 foot Monster Cable and wanted to move my sub, so I returned the Monster and ordered a 25' cable from Blue Jeans at almost 1/2 the cost. Great cable with very high-quality Canare RCA connections (much better than the Monster Cable).

You shouldn't have to spend a lot for 12 guage speaker cable. Try Parts Express (I got this 100' spool there and its very good) or HD as suggested in other posts. But as suggested, don't skimp on the component interconnects. I think Blue Jeans is a lot like Axiom - you don't have to pay a lot to get great quality.
